Ion Exchangers
in Plating Bath Analyses—A Forecast

PROOF THAT the
use of ion exchangers in metal-finishing operations is an accepted industry
technique
is evident in the consistently growing application of the
method in metal ion recovery from rinse waters and in the treatment of water
for process lines.

The article in this issue
by Mr. Gabrielson of Sweden tells of another valuable use for these materials.
While the use of ion exchangers
in analytical chemistry
is not new, the determination of boric acid, a major constituent of many
plating baths, through utilization of a sulfonic acid resin exchanger,
is novel and
of interest to platers. The procedure yields repetitively accurate results
and appears
to be a forerunner of additional practical applications for such “ion-trading” materials
in other-analytical methods.

By coincidence, convincing
extra evidence to such a belief is provided in this issue in the book review
by Dr. Harold
Read. He states that “one can
see many possible applications to the analytical problems of metal finishing,
particularly
to the determination of impurities and addition agents in plating baths.”

It
is a matter of record that the reporting of new methods has stimulated
further work along similar lines in the past. Through identical effort
in this instance,
improved techniques that offer practical advantages will be found and,
no doubt, will be published for the benefit of all. To this end, the
first-time release
of the new procedure is another reaffirmation of the dedicated aims
of the
Society as printed on the masthead of this journal.
